Thankfully we can use action masking — a simple technique that sets the probability of bad actions to 0 — to speed learning and improve our policies. TL;DR. We enforce constraints via action masking for a knapsack packing …

Feb 28 2021· So action(12) is invalid under that state. Some balls are not allowed to be picked under specific state. For example when the No.2 ball is marked Not Allowed to Pick，all actions with the No.2 ball like action (1 n) or (n1) are invalid. How to enforce these 3 constraints via action masking in rllib.

Jan 02 2020· Ray: ray 0.8.0.dev6. OS: Ubuntu 18.04.2. I''m trying to implement a self-play training strategy with PPO similar to the efforts of OpenAI''s Five (Dota) and DeepMind''s FTW (Capture-the-flag). My understanding is that these methods train a policy in a competitive manner: the agent plays a game against itself (same policy) as well as a mixture of

Apr 02 2020· Each action is repeated for four frames. All experiments except mouse are run using stable-baselines as only rllib supports mixed action-spaces. Other results are same between rllib and stable-baselines. Masked uses action-masking to remove unavailable actions and Minimal extends on this by removing all but necessary actions.
